Add support for two simultaneous controllers? Or are any conflicts expected running in two browsers simultaneously?

[cr08]

Just came across this project and looks amazing. I'm starting to dabble in some Euro/American Truck Sim stuff. In that space there are replacement shifter knobs for common wheel setups that adds extra inputs for the range/splitter functions (and in the case of the one I have, an extra push button for whatever). But these act as their own separate game controller from the wheel/pedals/shifter 'controller'. I'm not sure about all iterations that exist on the market but mine simply shows as 3 button inputs and that's it. On the shifter knob itself, it has two toggle switches with up being on, down being off.

Any chance support for two simultaneous controllers could be added for this? Or will it work running in two separate browser windows with each set for a different controller? I'd be willing to use that as a workaround.
